A theme is emerging in antiangiogenesis research: Small molecules stored within large proteins in the body can stop cancer cells from creating new blood vessels. Many enzymes that a tumor uses to invade surrounding tissue generate these angiogenesis inhibitors, but a tumor can locally override the effect of the inhibitors by generating angiogenesis stimulators. If researchers could shift this balance by increasing the concentration of endogenous angiogenesis inhibitors, they could potentially ar
